Ordering of factory setting (adjustment)
The intrinsically safe analogue interface PROFSI-B25091-ALG-YT allows to connect an YTTN6 temperature switch insuring safety be-tween hazardous area and safe area by means of galvanic isolation.
The Barrier allows the PFORSI3… to supply the YTTN6 temperature switch active or passive as to the wiring.
The output from the YTTN6 temperature switch 4 ... 20 mA and the two thresholds are available and the switches as relay outputs.
The connection terminals are all removable for easy connection of the cables.
